What a proud moment – behold the magic of cyclodextrins!

Our long-time friends and partners at Cyclarity Unveil First-Ever Clinical Data Demonstrating Excretion of Oxidized Cholesterol

Daniel Clemens recently presented the first data from Cyclarity Therapeutics‘ ongoing Phase I trial with UDP-003
Key highligths:

1. Safe excretion of 7KC (7-keto-cholesterol), a core driver of plaque associated with heart disease, stroke, inflammation, and age-related diseases, in humans suggests medicine could move beyond slowing heart disease to disease-modifying plaque reversal

2. First candidate from Cyclarity’s AI Platform reinforces promise of next-generation cyclodextrins to reverse disease and protect against future accumulation of harmful molecules and aging pathologies

Cyclarity’s UDP-003 binds directly to 7KC, the root cause of plaque buildup, then facilitates urinary excretion of it. Much like removing rust from metal, this approach directly targets a key source of damage within plaque with the goal of reversing and preventing atherosclerosis, a primary underlying cause of cardiovascular disease, and does so locally within the plaque to reduce risks of unintended systemic effects.

Plaque reversal is significant because research suggests that even a 1% reduction in coronary plaque burden has been associated with up to 25% lower risk of major cardiovascular events, such as heart attack or stroke.

In parallel, they are preparing for the launch of our Phase 2 trial, expected to kick off in early 2027.

Cyclarity Therapeutics is a clinical stage biopharmaceutical company engineering cyclodextrin molecules into simple, scalable, and affordable therapies that bind and remove toxic targets to address root causes of age-related disease.

No cholesterol – no pain?

Let’s start the week with an amazing Hungarian paper from University of Pécs.

Cyclodextrin (CD) derivatives deplete cholesterol from membrane rafts in TRPV1 and TRPA1 channels, reducing receptor activation in vitro, anticipating in vivo analgesic effects.

The tested CD derivatives are promising agents for exerting peripheral analgesia and anti-inflammation via cholesterol depletion, also supported by in vitro and in silico findings.

P2a Open Label Study to Evaluate 2-HPβCD in Subjects With Diabetic Kidney Disease

Today’s cyclodextrin: After a long time, HPBCD will be evaluated again in clinics, now in a new application.
ZyVersa Therapeutics Inc. is sponsoring this Phase 2a open-label, two- to three-center study to evaluate the clinical efficacy and safety of one dose level of 2-hydroxypropyl-β-cyclodextrin (2-HPβCD) given intravenously in adult patients with type 2 diabetes, diabetic kidney disease (DKD), and proteinuria.

According to the proposed mechanism of action, HPBCD entraps and passively removes intracellular cholesterol from the kidney. It is also believed to promote active cholesterol removal through up-regulation of cholesterol efflux transporters ABCA1 and ABCG1.

Methods for the treatment of chronic kidney disease

We are happy to announce the acceptance of a great patent from CarboHyde’s collaborator, Renatus, a pharmaceutical company focused on developing cyclodextrin-based cholesterol metabolism modulators. Renatus is a pharmaceutical company whose mission is to provide safe and effective treatment options for the treatment of numerous cholesterol-driven diseases such as chronic kidney disease, atherosclerosis, and Alzheimer’s diseases. The core technology of the company allows the normalization of cholesterol homeostasis by removal of excessive and toxic cholesterol within diseased cells without significant harmful effects on normal cells.

The lead asset RN-005 is a cholesterol metabolism modulator that has proven strong therapeutic efficacy in preclinical models of both diabetic kidney disease (DKD) and focal segmental glomerulosclerosis (FSGS) wherein dysregulated cholesterol metabolism causes progressive damage and loss of function in the kidney. The gamma-cyclodextrin oligomers are effective in cholesterol metabolism enhancement, cholesterol efflux, reducing inflammatory cytokine secretion, renal clearance of cholesterol, and/or reducing albuminuria. Therefore, the gamma-cyclodextrin oligomers can be used to treat or alleviate chronic kidney disease, symptoms thereof and/or complications related to chronic kidney disease.

New cyclodextrin dimer patent!

today’s cyclodextrin:
I am proud to share this new patent from Cyclarity Therapeutics not only because of the fantastic chemistry and excellent drug development but also as CarboHyde CSO Milo Malanga is among the inventors!

Cyclodextrin dimers are used to target 7-ketocholesterol, eventually to reverse atherosclerotic plaques.

Congratulation to Milo and the geat team at Cyclarity!

Oral alpha-cyclodextrin reverses cholesterol-crystal-induced retinal pathology in a rodent model of type 2 diabetes

Today’s cyclodextrin a study showing how alpha-CD treatment could be used in type-2 diabetes patients.
Cholesterol crystals were eliminated from the retinas of diabetic mice after oral alpha-cyclodextrin treatment. These findings demonstrate that T2D is associated with cholesterol crystal-induced retinal pathology that is improved using oral alpha-cyclodextrin. Improvements were observed in inflammation, neural function and visual response.

Cyclodextrin-loaded nanobubbles reduce cholesterol and atherosclerosis in vivo

While the uses of cyclodextrin as active ingredients is emerging both by the number of target diseases, companies developing them and types of CDs used, their efficient delivery remains a challenge.
The nanobubbles presented here could incorporate the CDs, accumulate in the atherosclerotic lesions, the release of CD and the reduce the total plaque area in the entire aorta and eventually reduce cholesterol level in mice plasma.

Cyclodextrins permeabilize DPPC liposome membranes: a focus on cholesterol content, cyclodextrin type, and concentration

Today’s cyclodextrin is a smart and very practical study, highlighting how different cyclodextrins added to a liposomal formulation could influence the release of the active load.

The results demonstrated that the CDs effect on the membrane depends on the CD type, CD concentration, and membrane cholesterol content. The investigated CDs exhibited an instantaneous permeabilizing effect promoting vesicle leakage of API from the various membranes; this effect increased with CDs concentration. Among the studied CDs, α-CD, β-CD, and RAMEB were the most permeabilizing CDs on the different membranes.

Treatment of hypertriglyceridemia with 2-hydroxypropyl-beta-cyclodextrin

Fascinating therapeutic application of cyclodextrins have been published by Beren Therapeutics. Earlier the company already patented the use in the therapy of familial hypercholesterolemia, now they propose using hydroxypropyl-BCD against hypertriglyceridemia.
In the 2nd patent composition and purification is reported of a compounds that has a surprisingly high DS (DS-10 being the main component), which composition is far from the materials used as excipients.

High-Cholesterol Diet in Combination With Hydroxypropyl-β-Cyclodextrin Induces NASH-Like Disorders in the Liver of Rats

We are hearing a lot about how the cholesterol complexation ability of certain cyclodextrins, especially hydroxypropyl-beta-CD can be used to treat various diseases, like Alzheimer’s, Niemann Pick type C, atherosclerosis, familial hypercholesterolemia and many more.
But can this be a double-edged sword? This fascinating research suggests that High-Cholesterol Diet in Combination With Hydroxypropylβ-Cyclodextrin Induces NASH-Like Disorders in the Liver of Rats
